I practice Kundalini Yoga, which is all about the meditation.
Yoga is to active the body and breath, allowing for a long meditation to be possible.
Usually the order is something like -
Mantra to focus and greet the Greater Knowledge (intuition, God, etc)
Poses to activate the root chakra and breath.
Kriya (set of poses) to focus on one facet of existence. Usually physically exhausting. Uses various types of breathing (long inhales, sharp exhales, breath of fire, shaped breath).
Meditation with pose and internal or external mantra.
Extended Shavasana (corpse pose), often with Gong.
Mantra for closing.
This has been the most effective method of clearing my mind. The practice carries over into real life as well. It's hard to explain, but with practice you can recall the energy/vibration of a pose/mantra whenever needed.
Through Kundalini, I have been able to take myself off of all the medications I had been on. I feel more energy, more empathy, and an overall more grounded approach towards how I interact with existence/consciousness.
